Application filed November 16, 1920,,$e1'ia1'N0.424.430. Renewed Augustfil, 1922. Serial No. 585,577.

and State of California, have invented cer tain new and useful Improvements in Gas Furnaces; and I do hereby declare the foll i to be a full, clear, and exact description of "the invention, such as will enable others skilled in the art to which it appertains to make and usethe same.

This invention relates to new and useful improvements in hot-air furnaces especially adapted to utilizegas as a fuel and has for its primary object the provision of a device of the above-stated character which is light in Weight and adapted to be suspended from the ceiling of a room or basement, thereby obviating the expense of constructinga special and expensive base or support forthe device.

A further object of this invention is the provision of a furnace of the above stated character which will be simple, durable and efiicient, and one which may be manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as the description proceeds the invention consists in certain novel features of construction, combination and arrangement of parts which will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side elevation illustrating a furnace constructed in accordance with my invention and suspended from the ceiling of a room or basement.

Figure 2 is a vertical sectional view illustrating the same.

Figure 3 is a similar View taken at right angles to Figure'Q.

Figure 4 is a transverse sectional View.

Referring in detail to the drawings, the numeral 1 indicates an outer shell or casing having its lower end closed and its upper end reduced and provided with a neck 2 for connection with a heat conducting pipe of any desired type and which is connectedin the usual manner to a register or any number of registers located at a point foreign.

to the location of the furnace. The shell 1 has located therein an inner shell 3 which terminates short of-the upper end of the shell 1 and has its upper end closed while its lowerend is formed to provide a fire box at. A passage 5 extends from the fire box 4 through theside of the shell 1; Theshelt 1 is secured tothe ceiling 6 of-a room or basement in any desired manner'so that the entire device depends downwardly-from the ceiling to a point in close proximity to the floor. I

A gas supply pipe-6 enters the fire, box 4-- and has connected thereto a gas burner. 7 of any well known construction-and which is. equipped with a suitable pilot 8' controlled by a valve 9.. The valve-9 also has associated therewith a main control valve 10 to which a rod 11 is connected. The rod ll'extends upwardly through the ceiling 6 'and is equipped with a suitable handlewhereby a person may readily control the flow of gas to the burner 7 from the room above the furnace and thereby obviate the necessity vof entering the basement or room below in order to increase and decrease the flowof gas to the burner.

A band orv ring 12 is located in the fire box for the purpose of protecting the inner shell 3 from excessive heat about the burner 7 or where the blaze from the burner strikes against the shell. The band or ring 12 supports a suitable deflector 13 positioned directly over the burner for the purpose of deflecting the flame against the band and also to cause the flame and heat to spread out during its passage upwardly in the inner shell 3. The inner shell 3' adjacent its upper end is provided with an'outlet opening let to which the upper end of a coiled pipe 15 is connected. Thecoiledpipe or flue 15 is disposed about the inner shell 3 and within the space occurin betweensaid inner shell 8 and the outer she 1' 1 and has its lower end 15 extending through the. outer shell for connection with a smoke stack or chimney in the usual manner. Thus, it will be seen that'the heat fumes or by-products will be taken from the upper end of the inner shell 3 and carried downwardly within the outer shell 1 a considerable distance and exhausted into a chimney or smoke stack, thereby giving a outlet opening 14 and spaced therefrom for the purpose of causing the heat and by-prodnets of combustion to first strike against the upper end of the inner shell 3 before entering the coiled pipe or flue 15.

Air inlet nozzles 17 are formed on the iower portion of the shell 1 and upon opposite sides thereof and have communication with the interior of the shell. The air intake nozzles 17 are adapted to be connected to air supply pipes 18 which may connect with registers in the room being heated so that the air in he room being heated will pass through said pipes and upwardly through the shell 1 and be eliiciently heated therein and passed back into said room by the way of the outlet neck 2 of the shell 1 and the heat conducting pipe connected thereto. The air supply pipes, if desired, may extend through the wall of the building to receive air from the exterior of the building.

.Vhile I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is:

A furnace comprising an outer shell having a heat conducting pipe leading from its upper end, air intake means for the shell, an inner shell within the outer shell and in spaced relation thereto and having its upper end closed, means supporting the inner shell above the base wall of the outer shell, a firebox in the inner shell, passage means to the firebox through the shells, a fuel burner within the firebox, a band adjacent the firebox within the inner shell to protect the shell against excessive heat, a deflector supported by said band, a flue leading from the inner shell adjacent its top and through the outer shell, and a deflector in the inner shell over the entrance of the flue to cause the heat and byproducts of combustion to strike said deflector before entering the flue.

In testimony whereof I affix my signature in presence of two witnesses.
